its early into the victorian season for them to start popping out bubs,i assume u keep them indoors,the spiny tailed egernias cann have there babys over a few days so keep your eyes peeled as im sure more will appear,they dont have big litters(egernia)but cunninghams are one of the egernias that generally have a higher number of young per litter,up to 8,but 4 to is more common,there is always a chance of only one though,but normally you get slugs to(unfertilsed ova)best thing to do is just watch the female,and let nature take its course,congrats to,good luck
